Free movie rental with Blockbuster Express
Blockbuster Express is the movie chain's answer to Redbox. You can rent movies for $1 a night without a membership, though you do need a credit card. Technically, movies rented through Blockbuster Express do not have late fees, but they charge you $1 per day until you return it.
You can also rent the movie online and then pick it up at the kiosk. If you sign up for its email newsletter you'll get a free movie rental code, too.
